> You shouldn't have to think everything perfectly though that you write. It's OK to say something dumb, or even offensive. It's not great, but no big deal either. I don't want to live in a world where we have to polish and double-check every thought that leaves our minds.
That's nice. And we shouldn't have to maintain physical appearances or be judged for it. We should just accept all of our imperfections, celebrating all forms of expression. But lookism and online-lookism are here to stay. Conventions of "good" info content are strengthened by karma/gamification, for every vote you give, including here on HN. It's noble to desire for a time when we can just all be ourselves, but with attention spans vanishing I don't think anyone will care.
